Sustainability is more than just a buzzword; it’s a critical engineering challenge demanding a comprehensive and precise approach.

In this article Edmar Cabra, Regional Sustainability Lead – MENA, explains why sustainable engineering solutions must go beyond certifications to deliver real, measurable outcomes.

While “Green” certifications for facilities like data centres might seem like a victory, they don’t always guarantee true sustainability. A ‘green’ certified data centre, for instance, could still exhibit high energy and water consumption, and significant emissions compared to a non-certified one. This underscores the necessity for sustainability strategies to deliver tangible results that encompass the total cost of ownership, looking beyond mere CAPEX or OPEX.

“True sustainability hinges on measurable impact.”

At its core, sustainability in engineering focuses on three pivotal areas: energy, water and carbon. These elements yield the highest impact across all sustainability categories, making them the prime targets for effective solutions. Addressing these issues requires rigorous engineering analysis –
– Identifying the problem
– Pinpoint immediate causes and contributing factors, and
– Meticulously plan for corrective or preventive actions
This systematic problem-solving approach is fundamental to achieving meaningful progress.

The Imperative of Data in Regulation Compliance

Real-world challenges in achieving sustainability are increasingly driven by evolving regulations. Consider the new Energy Efficiency Directive (EED) in the European Union, for example. It mandates significant energy efficiency improvements and transparent reporting for businesses, particularly those operating data centres. This legislation directly impacts how companies must manage their energy consumption and carbon footprint, fundamentally shifting from voluntary certifications to legally binding requirements. Such directives unequivocally highlight the urgent need for a data-driven approach.
In this rapidly evolving regulatory landscape, data centre operators, in particular, face escalating pressure to be transparent about their energy and water usage, as well as their carbon emissions. This is precisely where data becomes paramount. Accurate and comprehensive data is the linchpin for understanding current performance, setting realistic targets, and effectively tracking progress. Without such precise data, even the most ambitious sustainability goals remain aspirational. Therefore, the industry must proactively move towards robust data collection and analysis to not only meet these new obligations but also genuinely improve environmental performance.

Engineering for a Sustainable Future: Best Practices

Engineering solutions must be precise and bespoke. They must be meticulously tailored to deliver peak performance and minimise environmental impact in diverse environments, from the scorching desert heat of the UAE to the humid climates of Southeast Asia and the cold climate of the Nordics. This means leveraging advanced modelling tools to ensure that every Mechanical, Electrical, and Plumbing (MEP) system is the optimal fit for specific project needs and local climatic conditions. The industry needs to prioritise bespoke engineering that considers every variable, optimising for efficiency and resilience under real-world operating conditions.

“Engineering solutions must be precise and tailored. Generic approaches simply won’t suffice.”

Innovation as a Cornerstone of Sustainable Engineering.

The commitment to tackling these complex sustainability challenges is increasingly amplified by continuous research and development. A technology-backed solution approach is crucial, relentlessly seeking out and evaluating cutting-edge innovations. This involves actively partnering with leading manufacturers and technologists to ensure that the most advanced and effective solutions are seamlessly integrated into projects. This proactive embrace of innovation keeps organisations at the forefront of sustainable engineering, enabling them to consistently offer state-of-the-art solutions that push the boundaries of energy efficiency and environmental responsibility. The future of sustainable engineering relies on a collective dedication to innovation, knowledge sharing, and the practical application of new technologies.

By synthesising in-depth engineering analysis, data-driven insights, and a steadfast dedication to research and development, the industry can spearhead the transformation of sustainability from an abstract concept into a measurable and achievable engineering reality. This holistic approach, firmly rooted in precise engineering and technological advancement, is how businesses can not only meet but unequivocally exceed their sustainability goals, paving the way for a more resilient and responsible future. It’s about empowering organisations with the knowledge and tools to make informed decisions and implement solutions that genuinely contribute to a more sustainable world.

Computational Fluid Dynamics (CFD) is fast becoming essential to the evolution of AI scale data centres, where the density and complexity of compute workloads are reaching unprecedented levels. Maintaining performance and resilience in these environments demands more than traditional design, it requires precision engineering, proactive risk mitigation, and advanced simulation-based verification. CFD plays a pivotal role in delivering all three.

In this article, Ramamoorthy Sethuramalingam, Associate Director and Head of CFD explores how CFD supports smarter engineering decisions for AI-ready, high-density data centres, from rack-level airflow to site-wide heat rejection systems. 

Smarter Data Centre Cooling Strategies with CFD 

CFD empowers our engineering teams and clients to visualise and optimise airflow, pressure zones, and heat distribution across high-density environments. Whether designing a new facility or fine-tuning an existing one, CFD provides a predictive lens into system behaviour, preventing thermal hotspots, supporting uptime, and driving operational efficiency from day one. 

Internal Air-Side Cooling in AI Data Halls 

In conventional air-cooled halls, CFD identifies recirculation issues, airflow short circuits, and ineffective containment strategies. Using these simulations to design optimised cold-aisle and hot-aisle systems, ensuring even the most power-dense racks are cooled reliably, without over provisioning. 

Modelling Liquid Cooling Systems for High-Density Loads 

As air cooling reaches its limits, AI workloads increasingly rely on direct-to-chip cooling, immersion systems, and rear-door heat exchangers. CFD enables our engineers to model coolant 1-D flow paths, detect imbalances, and anticipate temperature deviations before deployment. It also allows simulation of failure modes (such as pump outages, power outages, equipment failures etc), so that robust contingency plans are embedded in the design. 

To support large-scale liquid cooling topologies, integrating 1-dimensional thermal and hydraulic modelling. This allows us to size pipework, optimise pump selections, and ensure consistent flow across parallel circuits. For AI-ready campuses, 1D and 3D simulations together deliver a holistic, scalable cooling strategy with built-in redundancy. 

Buffer Vessel CFD Optimisation 

Buffer vessels are critical for thermal inertia and flow stability. And using vessel mixing patterns, heat retention, and dynamic load responses, CFD guarantees that temperature fluctuations are smoothed out-even during power failure transient states like load spikes or component failures and ensuring IT reliability. 

External Plant Performance 

Chillers, dry coolers, and adiabatic systems play a central role in rejecting heat from IT to the atmosphere. CFD helps us evaluate the interaction between plant layout, prevailing winds, building geometry, and heat plumes. This insight is vital to prevent thermal recirculation, reduce fan energy, and maximise the effectiveness of external plant assets in any climate. 

Modular Pod-Level Simulations 

For rapid-deploy modular systems and containerised electrical pods, CFD delivers pre-installation design validation. Our CFD engineers test pod configurations to ensure airflow integrity, containment compatibility, and cooling adequacy before physical deployment reducing commissioning risks and accelerating rollout. 

At Black & White Engineering Ltd, CFD is more than a modelling tool, it’s a strategic asset. From rack-level detail to site-wide thermal resilience, our CFD-driven approach supports smarter, safer, and more scalable AI data centre environments. As compute intensity increases, so does our commitment to delivering engineering solutions that keep performance, sustainability, and reliability in perfect balance.

Balancing operational resilience with sustainability in data centre design is a complex, often contradictory challenge. While ensuring that data centres remain operational even during failures is critical, these measures can inadvertently increase the environmental footprint. How can the industry move towards more sustainable data centre operations without compromising on resilience? Scott Wilson Regional Sustainability Lead at Black & White Engineering shares his insights. 

The Trade-offs Between Resilience and Sustainability in Data Centre Design

Data centres are designed with redundancy to ensure uninterrupted service during plant failures. Redundancy configurations such as N+1, 2N, or even 2N+1 are common, providing backup equipment to maintain operations. However, this overengineering introduces several sustainability concerns: 

• Increased Embodied Carbon: More plant equipment means higher embodied carbon, particularly in MEP (Mechanical, Electrical, and Plumbing) systems. The additional structural steel and concrete required for oversizing further contribute to this carbon load. 

• Impact on Efficiency: Oversized equipment may lead to lower operational efficiencies in the real world. 

• Backup Power Reliance: Diesel-powered generators, which are often used for backup power, remain a major contributor to emissions. 

• Higher Resource Consumption: The need for increased plant provision and backup systems leads to more resource consumption. 

While redundancy is essential for resilience, these factors must be carefully managed to ensure they don’t conflict with sustainability goals. 

Location Matters: Reducing Carbon Footprint from the Start 

The location of a data centre can play a significant role in its sustainability. Data centres in colder climates, for example, can leverage free cooling, which reduces energy demand for cooling systems. This, in turn, lowers peak demand and reduces the size of required plant and backup systems. A smaller plant means less embodied carbon, as well as reduced redundancy needs and lower UPS and generator capacity. 

Innovations in Backup Power and Efficiency 

Modern technology offers several ways to improve efficiency and reduce emissions: 

• Modular UPS Systems: Load switching UPS systems allow individual modules to be powered off during low-demand periods, improving energy efficiency. 

• HVO Generators: Replacing diesel generators with hydrogenated vegetable oil (HVO) produces 10% of emissions compared to diesel, making it a more sustainable backup power option. 

Waste Heat Utilisation: Turning a By-product into an Asset 

One often overlooked but highly sustainable option is waste heat utilisation. Data centres naturally generate excess heat, but rather than allowing this to go to waste, it can be harnessed for other purposes. By connecting to district heating networks, data centres can transfer waste heat to nearby communities or industries, reducing the need for additional energy production. For this to be viable, significant investments in infrastructure are needed. Regions with existing networks, such as Denmark’s Fjenvarme Fyn, are leading the way in this regard. 

Water Source Cooling 

Cooling is one of the largest energy consumers in a data centre. By situating data centres near bodies of water, the demand for cooling can be significantly reduced. Water has a more consistent temperature than air, which helps to stabilise cooling requirements. Additionally, underwater or floating data centres, like Microsoft’s pilot project in the Orkney Islands, have shown promising results in terms of reduced server failure rates and increased energy efficiency. 

Liquid and Immersion Cooling Innovations 

Two innovative cooling technologies are gaining traction in the industry: 

• Liquid Cooling: This system eliminates the need for traditional CRAC/CRAH units, reducing potential failure points. It also cools chips more effectively, lowering the likelihood of failure and reducing downtime. 

• Immersion Cooling: This solution immerses servers in a cooling liquid, protecting them from contaminants and maintaining cooling even during power outages. Immersion cooling significantly reduces energy consumption and protects servers from ambient temperature fluctuations. 

These cutting-edge cooling methods not only improve resilience by protecting hardware but also help reduce the overall energy consumption of data centres. 

Striking the Right Balance 

As the data centre industry continues to evolve, the challenge remains clear: how can we design resilient, high-performing facilities while minimising environmental impact? By embracing innovative solutions such as modular UPS, HVO backup power, waste heat utilisation, and advanced cooling technologies, the industry can make meaningful progress towards more sustainable operations. However, finding the right balance between resilience and sustainability will require careful consideration at every stage of the design and operational process. 

By implementing these strategies, data centres can not only meet the increasing demand for digital infrastructure but also play a key role in driving a more sustainable digital future. 

At Black & White Engineering, we collaborate with developers to implement innovative solutions that balance sustainability in data centre design with resilience. If you’re looking to future-proof your data centre infrastructure, get in touch with us to continue the conversation.

The feasibility of microgrids and their potential advantages over nuclear-powered energy for hyperscale data centres is a critical discussion point in the energy sector.

Devan Moodley, Global Director – Power Systems & Infrastructure at Black & White Engineering, shares his insights on the evolving energy landscape and what it means for data centre operators.

Microgrids vs Modular Nuclear: What’s the best option for Hyperscale Data Centre Power Infrastructure?

Microgrids and grid independence have long been key considerations for major utility providers and power consumers. The growing integration of behind-the-meter renewables has shifted the role of distribution network operators, creating increased competition for grid connections. Data centre operators are now among those seeking alternative solutions to secure a reliable power supply.

Microgrids typically integrate renewables at the end-consumer level within the distribution network, usually at low voltage. These systems rely on a dedicated power source, historically including solar, diesel and gas generation. However, the large-scale power demands of hyperscale data centres require generation connections at the medium-voltage level, which only large gas turbines can currently support.

With net-zero targets pushing the transition away from gas, nuclear power is gaining attention as a potential solution. The development of modular nuclear generation plants is advancing rapidly, and if successfully deployed, they could provide clean, reliable energy at scale. This could have a transformative impact on both utility providers and energy-intensive industries such as data centres.

In the near term, supplementing grid supply with gas-powered generation may still be necessary. However, the extent to which this remains viable will depend on evolving environmental regulations. As cleaner energy solutions progress, microgrids, modular nuclear and other emerging technologies will play an essential role in addressing capacity challenges in the data centre sector.

Alternative Power Solutions That Haven’t Gained Mainstream Adoption

Most data centres are built in urban areas, while power generation facilities are typically located near fuel sources. This applies to wind, solar, coal and other energy sources. Finding alternative solutions that avoid significant drawbacks remains a challenge.

Open-cycle gas turbine plants are one potential option, offering flexible, on-demand power. However, they come with challenges such as emissions, noise pollution, and reliance on a stable gas supply. Another consideration is whether data centre operators are willing to host generating plants on-site, which would require a shift in operational strategy.

As the industry evolves, it is becoming increasingly clear that data centre owners and operators may need to transition into generating asset owners to secure reliable and sustainable power.

Managing Power Demands in the AI Era

The accelerating adoption of AI is driving unprecedented power demand. As data centres grow in scale and complexity, new solutions will be required to improve efficiency, including the development of energy-efficient chips, advancements in cooling system design and optimisation of electrical infrastructure.

One of the biggest challenges ahead is the introduction of new regulations. Stricter policies on carbon emissions, energy sourcing, and grid reliance could reshape the data centre industry. Developers and operators must take a proactive approach to future-proofing their facilities.

The industry is at a turning point. As energy demands continue to rise, forward-thinking power strategies will be critical in securing a stable and sustainable future for hyperscale data centres. To explore how these changes could impact your data centre infrastructure, get in touch with our team.

Alongside our existing Gurugram office, this new location in Delhi NCR’s business hub enhances accessibility for our teams while unlocking new engineering job opportunities in Noida.

A Prime Location 

Situated in Sector 16A Noida, the new office is positioned in a prime location with excellent connectivity, including direct access to metro links and public transport. Black & White employees will benefit from modern amenities and recreational spaces, ensuring a well-equipped and comfortable working environment.
The MEP Design team will be based in Noida, collaborating closely with our colleagues across the region and supporting projects and clients globally.

Supporting Our Global Expansion and the Data Centre Industry

The Noida office plays a critical role in our broader growth strategy, enabling us to expand our network and improve accessibility for employees in the Delhi NCR region. By establishing a presence in this new area, we are enhancing flexibility, improving work-life balance and strengthening our ability to attract and retain engineering professionals.

“At Black & White, we recognise that a healthy work-life balance is essential for employee well-being. In Delhi NCR, commuting time is a major factor in achieving this balance. By opening our Noida office, we are not only improving accessibility for current employees but also enhancing our visibility and presence in this key region.”– Khan Moid Hasan, Director

Future Plans for Our Noida Office

Our long-term vision for the Noida office includes scaling to over 100 employees by the end of 2025. This expansion aligns with our broader objective of fostering innovation within the data centre industry and delivering exceptional outcomes for our clients worldwide.

“This marks a significant step in Black & White’s growth. It opens new opportunities for our team to take on expanded roles and develop within the company. We are excited about the possibilities ahead and look forward to this next chapter.”– Ashish Tiwari, Director
